Surprising Findings

Despite significant reductions in LDL cholesterol and diastolic blood pressure, there was no reduction in coronary heart disease, stroke, or composite cardiovascular disease.

For decades, lowering LDL and blood pressure has been the gold standard for preventing heart disease. This study shows that even when those markers improve, the actual disease outcomes may not follow — challenging a core assumption in preventive cardiology.

Practical Takeaways

If you're a postmenopausal woman focused on heart health, don't rely solely on eating more veggies and cutting fat — consider other proven strategies like exercise, blood pressure control, or statins if recommended.
